<p>Hi <span class="user-mention" data-user-id="116155">@Jake Goulding</span> ; I was trying today to follow the instructions at <a href="https://github.com/shepmaster/rust/tree/silicon-bootstrap/silicon">https://github.com/shepmaster/rust/tree/silicon-bootstrap/silicon</a> . This is perhaps a silly question, but: Does one need to actually have <em>installed</em> the Xcode beta and use it as the default for clang for those instructions?</p>

<p>I wasn't sure from the instructions whether the use of Xcode-beta was just to get the right SDKROOT in place.</p>

<p>(The reason I ask is that I tried a couple times today to follow the instructions there, but kept hitting an error of the form <code>clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11.5'</code>)</p>

<p>I guess your instructions there do in fact say "You'll need to have <em>installed</em> the Xcode beta"  (emphasis added)</p>

<p><span class="user-mention" data-user-id="116083">@pnkfelix</span> to my knowledge, only Xcode 12 beta can target aarch64 apple hardware</p>
